Abstract
The invention relates to an emergency treatment method of chlorine effusion during producing a beta-hydroxyl-beta-methyl butyric acid. The method for emergently treating the chlorine effusion during the production of the beta-hydroxyl-beta-methyl butyric acid and derivatives thereof by a diacetone alcolol method comprises the following steps of: once chlorine effuses, immediately stopping dropping a sulfuric acid or hydrochloric acid solution, immediately adding sodium bisulfite, stirring for 0.5-1 hour; and then continuing dropping the sulfuric acid or the hydrochloric acid solution till a complete acidification, wherein the weight ratio of the sodium bisulfite to the diacetone alcolol as the raw material is 1:6-1:8. The chlorine effusion is caused by excessive sodium hypochlorite (NaOCl) aqueous solution during a haloform reaction and the chlorine is then generated by the reaction between the sodium hypochlorite and the sulfuric acid (hydrochloric acid) during the acidification. In the invention, the sodium bisulfite is used for neutralizing the excessive sodium hypochlorite, and generated sulfate and hydrochloride do not influence the extraction of HMB, thus the product quality is not influenced.
Description
(1) technical field
The invention provides the emergency processing method when chlorine is overflowed in a kind of diacetone alcohol method production HMB (be beta-hydroxy-Beta-methyl butyric acid, be also referred to as 3-hydroxy-3-methyl butyric acid) and the derivative process thereof, belong to the fine chemistry industry production field.
(2) background technology
HMB (is beta-hydroxy-Beta-methyl butyric acid, be also referred to as 3-hydroxy-3-methyl butyric acid) be leucic meta-bolites in the human body, HMB and derivative thereof can be used for promoting the animal muscle growth, strengthen mammiferous immunological competence, reduce cholesterol in human body and low-density lipoprotein (LDL) level to reduce the generation of coronary heart disease and cardiovascular disorder, can also help to strengthen the human body nitrogen fixing capacity, keep body internal protein level, therefore use very extensive.
The suitability for industrialized production of HMB and derivative thereof generally adopts the diacetone alcohol method at present, dripping sulphuric acid soln or hydrochloric acid soln then by haloform reaction carries out acidifying and makes HMB, and for reducing production costs, haloform reaction is a raw material with clorox (NaOCl) aqueous solution that is easy to obtain all.In process of production, have chlorine when carrying out acidifying sometimes and overflow, thereby cause the production plant environmental pollution, if untimely taking measures, the lighter makes the operative employee cough, have difficulty in breathing, and weight person makes the operative employee feel sick, vomit, fall in a swoon even causes life danger.When this thing happens, the measure of generally taking only was to open the window, start vent fan, made production plant keep air unimpeded, can not tackle the problem at its root.
(3) summary of the invention
The objective of the invention is to fundamentally address the above problem, the emergency processing method when chlorine is overflowed in a kind of safe and effective, beta-hydroxy-Beta-methyl butyric acid production process of not influencing quality product is provided with chemical process.
The object of the present invention is achieved like this: the emergency processing method when chlorine is overflowed in a kind of beta-hydroxy-Beta-methyl butyric acid production process, described method is in case find to have chlorine to overflow when the diacetone alcohol method is produced in beta-hydroxy-Beta-methyl butyric acid (HMB) and the derivative process thereof acidifying, stop to drip sulfuric acid or hydrochloric acid soln immediately, add sodium bisulfite (NaHSO at once
3), stirred 0.5～1 hour, and then continuation dripping sulfuric acid or hydrochloric acid soln is complete to acidifying, the weight ratio that feeds intake of wherein said sodium bisulfite and raw material diacetone alcohol is 1: 6～1: 8.
The invention has the beneficial effects as follows:
Clorox (NaOCl) aqueous solution was excessive when the reason that causes chlorine to overflow was haloform reaction, thus when acidifying clorox and sulfuric acid (or hydrochloric acid) reaction generation chlorine.The present invention neutralizes excessive clorox with sodium bisulfite, and the vitriol of generation and hydrochloride do not influence the extraction of HMB, so do not influence quality product.
(4) embodiment
The present invention relates to the emergency processing method when chlorine is overflowed in a kind of beta-hydroxy-Beta-methyl butyric acid production process, be when the diacetone alcohol method is produced in beta-hydroxy-Beta-methyl butyric acid (HMB) and the derivative process thereof acidifying in case find to have chlorine to overflow, stop to drip sulfuric acid or hydrochloric acid soln immediately, add sodium bisulfite at once, stirred 0.5～1 hour, and then continuation drips sulfuric acid or hydrochloric acid soln is complete to acidifying, and wherein the weight ratio that feeds intake of sodium bisulfite and raw material diacetone alcohol is 1: 6～1: 8.
Claims (1)
1. the emergency processing method when chlorine is overflowed in beta-hydroxy-Beta-methyl butyric acid production process, it is characterized in that: described method is in case find to have chlorine to overflow when the diacetone alcohol method is produced in beta-hydroxy-Beta-methyl butyric acid and the derivative process thereof acidifying, stop to drip sulfuric acid or hydrochloric acid soln immediately, add sodium bisulfite at once, stirred 0.5～1 hour, and then continuation drips sulfuric acid or hydrochloric acid soln is complete to acidifying, and wherein the weight ratio that feeds intake of sodium bisulfite and raw material diacetone alcohol is 1: 6～1: 8.
